WATER BACK FOR STOVES OR RANGES.

SPECIFICATION forming part of Letters Patent No. 656,687, dated August 28, 1900.

Application filed May 12, 1900.

' citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Water-Backs for Stoves or Ranges, of which the following is a specification.

This invention relates to certain new and" useful improvements in stoves and ranges, the object being to provide a stove or range with a Water-back which can be removed entirely from the stove without separating it from the stand-boiler, which object is accomplished by the employment of swinging joints or couplings which are arranged on a vertical line with each other and are interposed immediately between the water back and stand-boiler, the present invention being designed more particularly as an improvementupon my Patent No. 6et6,779, patented April 3, 1900, and by the constructionand arrangement of the parts as herein shown I am enabled to dispense with telescopic couplings and the packings incident thereto.

This invention consists in the combination with a stove or range having an opening through one of the side walls thereof, a door for closing the opening, a stand-boiler, and a water-back connected to each otherby pipes and swing-joints, the stove or range,the stand-" boiler and the water-back being so positioned one relative to the other thatthe water-back can be swung into the fire-pot or away from the same to entirely separate it from the stove or range.

My invention further consists in the arrangement of the parts and in the construction of the stove or range, as will be hereinafter set forth, so thatthe only movement of the water-back willbe in the arc of a circle, thus permitting the stand-boiler to be set up much nearer to the stove or range than it could be done with the arrangement illustrated in the patent hereinbefore referred to.

In the accompanying drawings, Figure 1 is a perspective View showing one arrangement of myinvention. Fig. 2 is a detail view showing the rear portion of a stoveor range with a slide which is used in connection with the door shown in Fig. 1. Fig. 3 is a detail sec tional view taken vertically through the door Serial No. 16.451. (No man.)

of the stove. Fig. 4: is a plan view showing amodified form of my invention. Fig. 5 is a sectional View through a swing coupling which is provided with a cut-off. Fig. 6 is a perspective View of a drop-door which can be used in lieu of the horizontally-swinging door shown in the other views.

. The stove or range A, as to its general con struction, may be of the ordinary type; but, as shown in Fig. 1, the side wall of the stove and a part-of the back wall is cut away to eX- pose the fire-pot and permit of the placing therein of a water-back B. The opening through the side wall of the stove is closed bya door 0, which is hinged to the stove and has at its end farthest from the hinges a part 0, which projects at right angles to the main portion of the door, and said part G has recesses o 0, into which tongues a a of a slide A will project when the door 0 is closed. The slide A may be movably connected to the rear wall of the stove by bolts, which pass through slots in the slide, and the door may have a suitable latch or equivalent means for keeping the same closed.

As the door is intended to serve as one of the walls of the fire-pot when the water-back is removed therefrom, I prefer to construct the door so that it will be convex on its inner surface, such construction enabling the door to better resist pressure from within, and if an ornamental appearance is desired I may attach an ornamental plate to the con- VGX plate of the door and have through said plate perforations, so an air-space will be present between the inner and outer plate. The recesses c c in the door 0 are on the same horizontal plane as the inlet and outlet pipes of the water back.

The stand-boiler D is set up near the stove or range and pipes d d extend from the usual points, and to the ends of said pipes are attached one of the sections of swing joints or couplings, the other section of said joint or coupling being attached to the inlet and outlet pipes 12 b, which project from the waterback. These short pipes and swing-coup lings provide the sole means for connecting the stand-boiler with the water-back, and the swing-couplings E E may be constructed'lso that when the water-back is swung to a certain point, which may be indicated upon the sections of the couplings, the water will be out off from between the stand-boiler and water-back. Bysuch an arrangement should an accident happen to the water-back the Watersupply thereto can be readily cut off and another water-back attached without in any way disturbing the water-supply. The swing joints or couplings are positioned in a vertical line with each other and are so placed with respect to the stove that when the water-back is swung in a horizontal plane in one direction it will be placed in the fire-pot and will form one of the walls thereof, and said water-back maybe covered by the door, which overlies the side and rear end of the water-back, and when in place the pressure from within upon the water-back will be resisted by the door which covers the same, the greatest pressure upon the door being near its hinges, the outer pressure at the other end being resisted by the couplings, which prevent any movement of the water-back except in the arc of a circle and in a horizontal plane.- The recesses c c in the door partially surround the pipes 19 Z), and said pipes by abutting against the tongues force the slide A rearward. The door not only covers the opening in the side wall of the stove or range, but also the cut-away portion of the rear wall, and permits a slight circulation of air between the end of the water-back and the angular part of the door sufficient to obviate warping of that part of the door."

In Fig. 4 of the drawings I have shown an arrangement whereby the water-back is inserted in the stove from the front, and it will be noted that such arrangement provides a water-back which occupies the rear portion of the fire-pot and the outer end portion thereof and that there is no possibility of the fuel coming in contact with the angular end of the door. This arrangement also permits the use of a drop-door instead of one that swings horizontally.

It will be noted in every instance that the only range of movement that the water-back has in placing the same Within the fire-pot or in removing the same from the stove or range is a horizontal movement in the are of a circle of which the center of the couplings is the center of the arc, and by such construction and arrangement the position of the stand-boiler may be varied to suit the requirements as to space and the position of the boiler. By lengthening or shortening the pipes the boiler may be placed either close to the stove or range or close to the wall, whereas in my prior patent it was necessary, by reason of the construction illustrated therein, to provide for a movement of the water-back greater than its length before the same could be entirely removed from the stove.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a stove or range havingan opening through one of the side walls thereof, a door for closing the opening, a stand-boiler having a water-back connected directly thereto by swinging couplings so as to be moved into the fire-pot of the stove, the door being adapted to close the opening through the wall of the stove and when the water-back is removed from the fire-pot to form one of the walls thereof, substantially as set forth. 7

2. The combination with a stove or range and its fire-pot, of a water-back, stand-boiler,

and means for connecting the water-back to the stand-boiler said means comprising pipes and interposed swing-couplings, an opening through an exterior wall of the stove of a size to admit the entrance of the water-back to the fire-pot, a door secured to the stove adjacent to the opening, said door serving to hold the water-back in the fire-pot and form one of the walls of the fire-pot when the water-back is swung beyond the stove, substantially as shown.

3.
